IMPROVEMENT IN SPINNING-MULES.

Specification forming part of Letters Patent No. 139,051, dated May-Q0,1873; application lrd February 15, 1cm.

To all whom it may concern:

15e it known that I, JOHN J. DEWEY, 0 Queechee, in the countv of Windsorand State or' Vermont, have invented a new and useful Improvement inSelt'- Operating Spinning Mules or Jacks, ot' which the following is aspeciticaton:

My invention consists ot' a combination, with the carriage of aspinning-mule, ot' gearing arranged tor facilitating the running ot' Thecarriage in by hand (first throwing oft' the driving-belt and turningrthe spindles slowly) when the bobbins are full and ready to be dotl'ed,so that the yarn may be wound a few times around the bottoms of thebobbins to fasten it, and then run down below the bobbins onto thespindles, so as to be held, when the bobbins are doii'ed, ready to berun upon the new bobbins. .By this meansI am also enabled to wind uponthe spindles the packing of line threads for holding the bobbins theretoby friction.

This kind ot' winding cannot be done when the spindles are driven in theregular way by the driving-belt and the machine is subject to theregular order of operations, because it must, of necessity, be doneaccording to the judgment of the attendant in each particular case,particularly in winding the packing on the spindles; hence I providegearing, by means of which, after throwing oft' the driving-belt, thecarriage may be run in with facility instead ot' pushing it in by adirect application of force; for, although it is possible for a strongman to push it in by main force, the exertion required is altogether toogreat, and for which some workmen would be entirely incapable with somemachines. I therefore provide a hand-crank and reducing-gear, so as tomake the operation easy for any spinner, and enable him to run thecarriage in with one hand while controlling the yarn by the followerwith the other.

In applying this hand driving-gear I avail myself ot' the toothed wheelused on some spinning-maehil'le carriages for certain purposes, andgearing with a toothed rack on the licor; but where such machines arenot of a spinning-mule provided with my improvement, and Fig. 2 is asection ot' Fig. l on the line .fr zr.

Similar letters of reference indicate corresponding parts.

A represents the carriage ot' the mule, B the rails or ways on which ittraverses, and C the wheels on which it runs. l) is the toothed wheelwhich is found on the carriage ot' some nulles, and E the toothed rackon the oor, with which it gears. With this wheel, whether already on themachine or specially applied for the end I have in view, I gear -a handcrank-sl'iai't, F, by means of the counter-shaft Gr, bevel-wheels H, anda pinion, I, or any other equivalent means. The pinion is much smallerthan the wheel, and adds considerably to the leverage of the crank, andthus makes it easy to run the carriage in by hand. Besides theapplication of this gearing to the carriage, 1 apply a lever or handle,K, to the follower-rod L, so that I can, with one hand, move thefollower-wire M down further than it is4 moved by the automatic devicesin the regular operations ot' the machine, and thus cause the yarn orthread to wind down below the bobbins N onto the spindles O, as beforestated, while I am forcing the carriage in with one hand by thecrank-shaft F.

It will be readily seen that with these con-.

trivances I can wind the yarn on the base ot' the bobbins or on thespindles, as I wish, and control the winding as needed.

It', in winding on the tine yarns or packing for holding the bobbins tothe spindles, I do not get enough on, as I probably will not, by oncerunning the carriage in, I can shift the driving-belt on and run thecarriage out by it, at the same time spinning the threads, and thenshift it oft' and run the carriage in again by hand, repeating theoperations as many times as I may wish to do.

Having thus described my invention, I

claim as new and desire to secure by Letters 2. In n spinning mule orjack having gear` Patenting;` for running the carriage in by hand, as 1.The combination, with a spinning mule above described, a lever, K,combined with or jack, of a hand-crank and reducing-greatthefollower-rod L, substantially as specified.
